2 Claims.

i This invention relates to a portable rotary adjustable seesaw.`

An object of the invention is the construction of an efficient amusement apparatus, in the nature of a seesaw, whereby the operators will not only obtain a great amount of pleasure or amusement, but will be greatly benefited in health by reason of the amount of exercise secured during the operation of the apparatus.

Another object ofthe invention is the construction of a rotary seesaW which is provided with simple and efficient means for adjusting the teeter board to accommodate children of different weight and height, during the operation of the apparatus.

A still further object of the invention is the ,d provision of novel angle locking sockets in the standards of a seesaw, whereby an ordinary bar is used for supporting a teeter board in different 0 horizontal positions to accommodate children of different heights in using the apparatus for exhilar-ating and beneficial exercise.

With the foregoing and other objects in View, my invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a view partly in section and partly in side elevation of an apparatus constructed in accordance with the present invention, while Figure 2y is a top plan view of the same, showing one of the standards in horizontal section.

Figure 3 is a sectional view taken on line 3 3, and looking in the direction of the arrows.

Figure 4 is a bottom plan view of the rotary platform.

Figure 5 is an enlarged fragmentary perspective view of the apparatus, showing particularly part of one of the standards and part of the teeter board.

Figure 6 is an enlarged sectional view of one of the castor devices.

Referring to the drawing by numerals, I designates a sectional base comprising an upper section 2 and a lower section 3. Fastened to the upper section 2 is a block 4. Extending through block 4 is a Vertic-al shaft 5. An enclosing casing 6 is preferably fastened by screws 'I to the upper section 2.

A rotary platform 8 is normally within casing 6, with shaft 5 extending through central aperture 9. A plurality of castor devices IIJ are fastened to the bottom of the rotary platform 8. These castor devices travel over the upper section 2 as clearly shown in Fig. 3.

A pair o-f vertical standards II is secured to the rotary platform 8. On the inner face of each standard I I are a number of angle locking sockets I2 for receiving the supporting bar I3, which bar is round or circular in cross section. It is to be particularly noticed that the angle locking sockets of one standard open upon a side edge different from the opening of the sockets in the other standard. By reason of this novel structure, bar I3 is more securely retained in its seated position, against accidental displacement.

A teeter board I4 is provided which is furnished with notches I5 on its under face. These notches receive the bar I3. By reason of these notches the teeter board can be quickly adjusted horizontally to accommodate children of different weight at the ends of the board, whereby the board can be evenly balanced, during operation.

By reason of the bar I3 being of the same size throughout its length it is immaterial which end is presented to either standard and its particular sockets, as the size of the sockets in both standards is the same, and the bar can be quickly adjusted from one set of sockets to another, in a horizontal plane.

The operators of the apparatus rest at I 6 on the teeter board I4 with their hands gripping the bars I'I, which bars are secured on the support I8; this support is represented as being a horses head and neck.

While I have described the preferred embodiments of my invention and illustrated the same in the accompanying drawing, certain minor changes or alternations may appear to one skilled in the art to which this invention relates during the extensive manufacture of the same, and I,

therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.

What I claim is:

1. In a device of the class described, the combination with a platform, of a pair of vertical standards on said platform, each standard provided on its inner face with an elongated socket, said sockets of the standards having their upper ends opening in opposite directions upon the edges of said standards, a detachable bar seated in the bottoms of said sockets, and a teeter board resting on said bar.

2. In a device of the class described, the combination with a platform, of a pair of vertical et opening on the other standard, a. detachable bar insertable in said pockets through the openings for transverse locking engagement in said blind sockets, and a teeter board resting on said bar.
